Could Spain have preempted forever France's conquest of Algeria?

Could Spain have preempted forever France's conquest of Algeria? By conquering its northern coast at any of the following points, the 1500s, the 1600s, the 1700s, or the 1815-1830 timeframe, and - more importantly, holding the land on a regular basis through the mid 20th century, through any period in which France might have been interested in making a colony of it? (IE, if the French ever grab it in a war of one of the Louis or a Napoleon, or another power grabs it, is just a short term occupation and Spain gets it back post-bellum). Interested in both a Spanish Algeria, however far back or recent its heritage goes, and an Algeria-less France.

Probably not without massive butterflies elsewhere at minimum.

Spain had Oran and Mers El Kébir from 1509 to 1708, and 1732 to 1792.
Having the Spanish-Algerian of 1775-1785 end in Spain's favor also would help. Spain gobbles up the coast between Algiers and Oran, as well as seizing Bone for itself. With the piracy issue ended and Algeria a Spanish vassal primarily, France has no reason to march in.

Spain curtailing Barbary piracy has interesting possible knock-on effects.
